ABSTRACT
Bubble point (L + V f L) and dew point (L + V f V) pressures were measured for the binary system CO2 + CHF3, using Cailletet equipment. The measurements were carried out for the whole mole fraction range and for temperatures from 263 K up to the mixture critical points. The experimental data were used to determine binary interaction parameters for the Peng-Robinson equation of state with a Stryjek and Vera modification (PRSV) and a Margules-type binary interaction parameter.
